Structurally, 87-88-7 YJ8L3BB7Y4 Chloranilic acid p-Benzoquinone, 2,5-dichloro-3,6-dihydroxy- 2,5-Cyclohexadiene-1,4-dione, 2,5-dichloro-3,6-dihydroxy- 2,5-Dichloro-3,6-dihydroxybenzoquinone 4-08-00-02707 (Beilstein Handbook Reference) AI3-61846 BRN 1875040 p-Chloranilic acid 2,5-Dichloro-3,6-dihydroxy-p-benzoquinone 2,5-Dihydroxy-3,6-dichlorobenzoquinone EINECS 201-780-7 NSC 6108 p-Quinone, 2,5-dichloro-3,6-dihydroxy- UNII-YJ8L3BB7Y4 (C6H2Cl2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 208.98 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
